Described as a "sexi space bunnygirl," SnowBuni often appears as a secret agent or agent provocateur in a science fiction setting, including robots, spaceships, hidden colonies in the Earth/Sol solar system, and secret, high-tech enclaves hidden within the human population on Earth itself. She works for a quasi-military Sylvalagi institution known as Blue Spring, but she spends much of her time undercover in the human population. Her favourite hobbies include winter sports, and an appetite for ice cream, hence her name.

Her usual enemies include her sister HoniBuni (a raven-haired bunnygirl, also described as her half-sister), and an eclectic mix of ghouls, zombies, aliens, mad scientists, robots, disembodied spirits, and lecherous politicians.
